The invention relates to a recombinant adenovirus comprising an albumin-binding moiety on the outer surface of the adenoviral hexon protein, pharmaceutical compositions containing it and its medical use. Particularly, the invention relates to an oncolytic adenovirus comprising a sequence encoding an albumin-binding moiety inserted in the hypervariable region 1 (HVR1) of the hexon protein coding sequence and its use in the prevention and/or treatment of cancer.

This document provides adenovirus vectors and methods and materials related to using adenovirus vectors. For example, adenoviruses for delivering nucleic acid encoding one or more immunogens (e.g., one or more immunogens associated with a pathogen causing an infection) to cells within a mammal such that the mammal produces an effective immune response against the immunogen(s) are provided.

Disclosed herein relates to a replication competent recombinant adenovirus comprising restriction enzyme sites in an E3 region to insert a gene of interest. Also disclosed herein is a method for generating the replication competent recombinant adenovirus and a pharmaceutical composition comprising the adenovirus for use in treating a disease or a condition.

Described herein are cell lines for recombinant adeno-associated virus (AAV) production, cell lines for AAV-implemented protein production, and cell lines for use in titering AAV; methods of making each of those cell lines; and methods of using each of those cell lines. In some aspects, the cell lines disclosed herein may be used in a manufacturing process that is seed virus-free, helper virus-free, and transfection-free that uses synthetic elements to control viral genes in a stable cell line.

The present invention relates a targeted delivery system for siRNA or antisense technology. In one embodiment, the invention provides for a method of treating cancer by administering a therapeutically effective dosage of HerPBK10 combined with siRNA, resulting in the inhibition of Her2 expression and cell death. In another embodiment, a plurality of HerPBK10 combined with siRNA form a nanoparticle.

A recombinant vector comprises simian adenovirus 43, 45, 46, 47, 48, 49 or 50 sequences and a heterologous gene under the control of regulatory sequences. A cell line which expresses simian adenovirus 43, 45, 46, 47, 48, 49 or 50 gene(s) is also disclosed. Methods of using the vectors and cell lines are provided.

Synthetic adenoviruses with tropism to bone tissue are described. The synthetic adenoviruses include an adenovirus type 11 (Ad11) fiber protein or a chimeric adenovirus fiber protein having an Ad11 knob domain. The synthetic adenoviruses can also include a transgene, such as a reporter gene or a transgene encoding a factor that promotes bone regeneration or repair. Use of the synthetic adenoviruses to target bone tissue and/or to promote bone repair or regeneration is also described.

Synthetic adenoviruses with liver detargeting mutations and expressing an adenovirus type 34 (Ad34) fiber protein, or a chimeric fiber protein with an Ad34 knob domain, are described. The synthetic adenoviruses traffic to sites of tumors. Use of the synthetic adenoviruses for delivering diagnostic or therapeutic transgenes to tumors are also described.

A compound for the sequestration of undesirable neutralizing antibodies against viral vectors in a patient. The compound includes an inert biopolymer scaffold and at least a first peptide n-mer of the general formula P ( - S - P ) .sub.(n-1) and a second peptide n-mer of the general formula P ( - S - P ) .sub.(n-1); wherein, P is a peptide with a sequence length of 2-13 amino acids and S is a non-peptide spacer, independently for each of the peptide n-mers, n is an integer of at least 1, each of the peptide n-mers is bound to the biopolymer scaffold. Independently for each occurrence, P has an amino-acid sequence including a sequence fragment with a length of at least six amino acids of a capsid protein sequence of a viral vector. Compositions including the compound and sequestering and inhibiting methods are also provided.

A fusion gene, a recombinant novel coronavirus high-efficiency immune DNA vaccine, a construction method and use thereof are provided. The immune DNA vaccine ZD-nCor19 provided herein uses RBD protein, residues 301-538 in the S2 subunit and residues 138-369 in the N protein of the novel coronavirus as target antigens, and has specific immune synergism molecules introduced at suitable positions, and thus can simultaneously efficiently induce humoral immunity and cellular immunity, and can avoid safety problems associated with ADE that may be generated by the full-length S protein and the full-length N protein, thereby achieving dual effects of prevention and treatment. The vaccine can be used as a safe, efficient and stable vaccine variety against novel coronavirus infection.
